  Method and system for antenna architecture for wcdma/hsdpa/hsudpa diversity and enhanced gsm/gprs/edge performanceUSPTO Application #: 20080080418Title: Method and system for antenna architecture for wcdma/hsdpa/hsudpa diversity and enhanced gsm/gprs/edge performance Abstract: Methods and systems for antenna architecture for WCDMA/HSDPA/HSUDPA diversity and enhanced GSM/GPRS/EDGE performance are disclosed. Aspects of one method may include receiving, for example, WCDMA, HSDPA, and/or HSUDPA signals via a plurality of antennas The wireless terminal may also receive and/or transmit packets using, for example, GSM, GPRS, or EDGE, that do not require simultaneous use of multiple antennas by antenna switching among the antennas. The number of packets that may be received or transmitted before switching to another antenna may be pre-determined or may be dynamically changed. Accordingly, each antenna may receive or transmit a pre-determined number of packets or specified number of packet that may be dynamically changed before being switched to the next antenna Each of the plurality of antennas may be reconfigured to operate via at least one of a plurality of different center frequencies within a specified range when receiving or transmitting RF signals.

FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0027][Not Applicable] [MICROFICHE/COPYRIGHT REFERENCE] [0028][Not Applicable] FIELD OF THE INVENTION [0029]Certain embodiments of the invention relate to wireless communication, More specifically, certain embodiments of the invention relate to a method and system for an antenna architecture for WCDMA/HSDPA/HSUDPA diversity and enhanced GSM/GPRS/EDGE performance. BACKGROUND OF THE INVENTION [0030]Wireless devices use one or more antennas to receive RF signals. However, signals received by an antenna may be affected by a transmission path taken by the signals, as well as by characteristics of the receive antenna. For example, the transmission path may comprise obstacles, such as, for example, buildings and/or trees that reflect and/or attenuate transmitted signals. In addition to obstacles in the transmission path, a receive antenna may also not be tuned to receive the frequencies for the desired channel For example, actual receive circuitry may deviate from the designed receive circuitry due to tolerances of real-world devices and/or manufacturing deviations. Additionally, the receive antenna may also receive interfering signals in the desired channel that may reduce the signal-to-noise ratio, thereby increasing the difficulty of demodulating the desired signal. If the interfering signals are strong enough, the receiving wireless device may not be able to properly receive and de-modulate the received signal. [0031]Some wireless communication protocols may require use of multiple antennas for reception and transmission, where each of the multiple antennas may communicate received RF signals to separate RF front ends, and where the multiple antennas may transmit at the same time. However, simultaneous transmission via multiple antennas and simultaneous operation of a plurality of RF front ends utilizes additional power consumption that may be generally undesirable, especially if the wireless device's power source is a battery. [0032]Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings. BRIEF SUMMARY OF THE INVENTION [0033]A system and/or method for an antenna architecture for WCDMA/HSDPA/HSUDPA diversity and enhanced GSM/GPRS/EDGE performance, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
